Hi everyone.
I have a customer that wants to use #18 wire to power a 3/4 hp motor.
208 volts, 3 phase, neutral & ground. 10 amp breaker feeding a VFD powering the motor
I have always used #14 as the minimum.
Before i submit my report, i wanted to cite the code for the #14 wire size, but cannot locate it.
What is the minimum wire size allowed for powering a 3 phase motor?
Please cite the code, if i'm wrong, i would definitely like to know.
Since i cannot cite a code, all i can do at this point is make a recommendation.
Thanks in advance,
James
